Mini Story: What It Feels Like on Test Day

Imagine you sit down at 8 a.m.:

  1. Bubble your info, hear directions, and then Section I starts: 90 minutes of rapid-fire questions with graphs, tables, and short scenarios about pollution, energy, ecosystems, and climate.
  1. After a brief break, you jump into Section II: now you’re writing, showing math, proposing solutions, and explaining impacts.
  1. By the time you’re done, it’s been around three hours on-site, but the official exam clock only counted 2 hours 40 minutes.
